Dear list,
I have this minimal sample:
\setupbackend
[format=PDF/A-3a,
intent=sRGB IEC61966-2.1,
profile={sRGB.icc,default_gray.icc},
level=0]
\setuptagging[state=start]
\setupcolors[cmyk=no]
\startTEXpage[offset=1em]
\externalfigure[transparent]
\stopTEXpage
\stoptext
The external figure is available from
http://pdf.ousia.tk/transparent.pdf (and output file at
http://pdf.ousia.tk/transparent-pdf-a-3a.pdf).
Using veraPDF (http://verapdf.org/), the output document doesn’t comply
with the validation profile requirements.
As Luigi wisely predicted, external images may be problematic.
I get one error, because of the color of the external figure:
https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and-3-rules#rule-6243-2.
The PDF object in question is the following:
12 0 obj
<<
/Type /XObject
/Subtype /Form
/FormType 1
/BBox [ 0 0 316.896 215.5669 ]
/Group <<
/Type /Group
/S /Transparency
/I true
/CS /DeviceRGB

/Resources 21 0 R

stream
q
0.188235 0.392157 0 rg /a0 gs
28.348 187.219 260.203 -158.871 re f
Q
endstream
endobj
Well, this is a minimal sample, but my real document is much bigger. Is
there any way to convert the stream to something that ConTeXt can handle
directly?
Many thanks for your help,
Pablo
